hey guys.not sure of im posting this in the right place if not sorry. i was having some serious issues with black slime all over the crushed coral in my tank. the guy at the LFS suggested ultralife red slime remover. he also said that i probably need circulating pumps to officially cure the problem since i only have one powerhead moving the water in my tank. I put the red slime remover in and it seems to be working. its been about 24 hours now. the only thing that's concerns me is that the water is kinda fizzling like i put alka selter in it.mostly at the outlet for the protein skimmer. is this normal?\r\n\r\nI also think i had my lights on way to long and that was contributing to the problem.
